What Is Vegan Leather?
Vegan leather is artificial, synthetic, or “faux” leather made from agricultural waste products and sustainable biomaterials. It can also be made from polymers like polyurethane and other recyclable materials.
Vegan leather is an alternative to animal leather and is made without using any animal products. It's environmentally friendly,
biodegradable, and animal-cruelty-free.
What Is Vegan Leather Made of?
Raw materials for vegan leather usually come from agricultural waste sources. Some of the materials most commonly used to manufacture vegan leather are:
Polyurethane and polyvinyl chloride. Synthetic leather is made using recycled plastic materials like polyurethane and
polyvinyl chloride. Many people choose to avoid this kind of vegan leather, as its manufacture contributes to the
depletion of fossil fuels.
Cork. Cork is a great alternative to plastics and animal skin for making vegan leather. Manufacturers can even get it from
corkwood trees without damaging the trees.
Cactus. Cactus is another innovative animal-skin replacement used to make vegan leather.
Kombucha cellulose or SCOBY.Kombucha, or kelp tea, is a fermented sweet drink made using a symbiotic culture of bacteria and yeast, also called a SCOBY. The bacteria and yeast share nutrients and ferment the tea. Over time, they multiply and form a mass of cellulose, called a “mother.”
The mother floats on top of the liquid and takes the shape of the container. Within a few weeks, it grows as much as 10 millimeters thick. The mass of cellulose is harvested to make new batches of kombucha. However, it can also be used to make fully biodegradable leather.
After harvesting the mother, manufacturers wash, oil, and air-dry it to obtain a flexible, leathery sheet. They then cut the material in strips and stitch, glue, or mold it into new shapes.
Mushroom.Mushrooms grow through a network of threads called mycelium. Manufacturers use it to make vegan leather. The mycelium grows within a few weeks and can be easily processed using mild acid, alcohol, and vegetable dyes to modify it. The material is then compressed, dried, and textured for use. Mushroom or mycelium leather closely resembles animal leather in appearance and strength.
Pineapple. Pineapple leather or Pinatex is vegan leather made using natural
pineapple leaf fibers, petroleum resin, and thermoplastic
polyester.
Yeast collagen. Biofabricated vegan leather can be made using the skin protein
collagen obtained from yeast in a laboratory.
Silicone. Silicone leather is made from refined silicone material. It is similar to plastic-based materials, but more eco-friendly and durable.
Bacterial cellulose and agricultural waste. Similar to SCOBY, bacterial cellulose can also be harvested, dried, and used to make vegan leather. Agricultural waste like maple leaf pulp, apple peels, and fruit pulp can be good sources of bacterial cellulose.
